- JwtTokenService back-dates nbf by the 30 s validation skew so a peer central whose
clock lags the issuer accepts a fresh token after failover.
- RoleMappingCacheSeconds = 0 routes RoleMapper to the matched-rows loader (old cost)
instead of loading every Deployer mapping's scope rules per call.
- RoleMappingCache / SecurityOptions / Component-Security.md describe Invalidate() by
its contract plus the TTL, not by a call site.
- Tests: HS512 with the same key, issuer/audience mismatch, lagging-peer nbf, TTL-0
matched-only reads, refresh-vs-Invalidate generation race.
